We are thinking about switching from oil heat to a geothermal system to heat and cool our 1200 sf cape in western massachusetts. If you have a geothermal system are you happy with it? Have you had any problems? How much did the conversion cost? What are the monthly costs associated with it? Do you know of a reputable installer in our area?
